20-30t Li-ion Tow Tractor
1. The service brake system is standardly equipped with front wheel disc type, rear wheel drum brake, and hydraulic power assisted brake for better braking effect;
2. Five-in-one controller (traction motor control, steering control, DC-DC, high-voltage power distribution and air pump control) is selected for good compatibility; the lithium battery and the control system communicate through the CAN bus to ensure the safe use of the battery, which is free-maintenance, with good safety and long service life;
3. Adopting full hydraulic transverse cylinder power steering axle to realize the front wheel steering, with high efficiency, light manipulation and long service life characteristics;
4. The use of dual power supply (high voltage / low voltage) steering motor to drive the gear pump to provide power for the transverse cylinder steering axle to achieve front wheel steering, in the case of sudden power failure of high voltage power, the low voltage battery can drive the steering motor to work, and the safety of the driver is further enhanced;
5. Easy and efficient operation of the towing hook; self-locking function effectively avoids the hidden danger of trailer disconnection caused by misoperation or bumps, high safety.
